Oh, I get it now.. I'll do the modification and upload the new version
to ego. Thanks! :)
Just for curiosity...why did that (using "new" on "new_with_range")
worked on 3.4/3.6? Should I be worried and provide an update for those
versions too? Because I use 3.4 at my pc (Debian Wheezy) and my spouse
uses 3.6 on hers (Ubuntu Quantal) and both works fine with that wrong
syntax.
